Goodfellow offers 89 variations of single crystal tin discs. These high-purity crystals have no grain boundaries and a specific orientation, making them ideal for applications in fundemental research. The tin discs can serve as crystal monochromators or analyzers for x-rays and neutrons. Their precise structure also enables investigations into materials properties and catalytic chemistry. With no defects, the oriented tin crystals support fundamental physics research as well. By customizing the purity, orientation and dimensions, Goodfellow provides researchers with ideal tin crystal specimens.
